xfdump: report to the host that a dump is available

Browse Source 
As suggested by @3d-gussner, announce to the host that a dump is
available for retrieval using an action "dump_available".

Any kind of dump is announced (even if manually triggered).

To avoid reading from xflash twice, remove some duplication and return
the crash reason directly in xfdump_check_state().
